Oh Dear: cost, fit and limits
Oh Dear is a website and server monitoring service for developers and agencies that checks uptime, certificates, domains and ports, and runs AI-powered checks where the user describes in plain English what should work and an AI tests it in a real browser.
What to know first
Oh Dear prices by the number of sites and servers rather than by monitor, starting at $17 per month for two and rising to $439 for 200, with custom pricing beyond. The pricing page says every plan has the same features, including single sign-on, so the tier only sets capacity. Monitoring data is stored in Belgium. Prices exclude VAT, and annual billing gives two months free.

Who Oh Dear is best for
Agencies with many small client sites
Per-site tiers from 10 to 200 sites let an agency price monitoring per client, and identical features on every plan keep upgrades simple.
Developers who dislike writing browser scripts
The plain-English AI check describes what should work, then runs it in a real browser and reports what it found, replacing a hand-coded script.
Security-minded site owners
The port scanner flags unexpected open ports, and blocklist checks cover spam and ad-block lists, which goes beyond a simple availability ping.

What Oh Dear does
- AI-powered browser checks
- You write in plain English what should work, an AI runs it in a real browser and the report says what it found, so a broken form can surface without a script.
- Port scanner
- A scanner flags open ports you did not expect on monitored servers, which catches a forgotten database port that an uptime ping would never notice on its own.
- Certificate, domain and blocklist checks
- Checks cover certificate expiry, domain expiry and listings on spam and ad-block blocklists, so mail trouble and expiring assets are watched next to plain uptime for every site.
- Notifications and sign-in
- Alerts go to Slack, email, SMS, webhooks, Teams and PagerDuty as the plan page lists them. Single sign-on works with Okta, Microsoft Entra ID and Google Workspace on every plan.
How Oh Dear handles your data
The privacy page states that monitoring data is stored in Belgium, giving EU data residency, and the vendor offers a data processing agreement that every customer can sign plus a public sub-processors list. No certification is stated on the pages we read, and neither is a retention period. The pages did not say whether customer data trains models, so ask how the AI browser check handles the content of pages it visits.
Where Oh Dear falls short in practice
- No free plan. Access starts with a trial and then $17 a month, so a hobbyist with one site pays more than on tools that give away 10 to 50 monitors.
- Capacity is counted in sites. A company with a few large applications pays by site and server count, and the pricing page does not say how many individual checks it can run on each one.

Oh Dear: common questions
What is AI-powered monitoring at Oh Dear?
The home and about pages describe it as telling the service in plain English what should work, after which an AI checks it in a real browser and reports what it found. It replaces writing a scripted browser test. The pages we read give no accuracy figures, so run it on a flow you know well first.
How much does Oh Dear cost?
Prices are in USD excluding VAT: Solo $17 per month for 2 sites and servers, Freelance $55 for 10, Studio $109 for 25 and Agency $165 for 50. Larger steps reach $439 for 200, with custom pricing beyond. Annual billing gives two months free, and there is a 30-day money-back guarantee, as of November 2026.
Where does Oh Dear store monitoring data?
The privacy page says monitoring data is stored in Belgium, which it presents as EU data residency. A data processing agreement is available to every customer, and a public list of sub-processors exists. The pages we read did not give retention periods, so confirm that point if your policy needs one.
Does Oh Dear offer single sign-on on every plan?
Yes. The pricing and feature pages say SAML 2.0 single sign-on with Okta, Microsoft Entra ID and Google Workspace is included on every plan, not reserved for Enterprise. That is unusual in this category, where SSO often sits behind the top tier, and it helps small agencies with strict client contracts.
Is there a free trial at Oh Dear?
Yes. The pricing page offers a free trial without a credit card, and a 30-day money-back guarantee after you pay. There is no permanent free plan on the pages we read. If you only need ping checks for one hobby site, a free tier elsewhere will cost less.
